Answer:
- partial products: 0.25, 1.5, 0.50, 3
- Zoe spent $5.25 on apples
Step-by-step explanation:
The partial products are apparently derived by multiplying parts of each value on either side of the decimal point:
1.5 × 3.50 = (1 + 0.5)(3 + 0.50) = 1×3 + 0.5×3 +1×0.50 +0.5×0.50
= 3 + 1.5 + 0.50 + 0.25 . . . . . partial products
Their sum is ...
3 + 1.5 + 0.50 + 0.25 = 5.25
Zoe spent $5.25 on apples.
Year 1: $110
Year 2: $121
Year 3: $133.10
Total interest: $33.10
Since x is the length, then x+7 has to be the width.
The area of a rectangle can be found via the formula :
A = length * width
So if we replace the area with the given number (170) and the length, and width, with what we assumed, we get..
170 = x * (x+7)
[which is.. ]
170 = x^2 +7x
0 = x^2 +7x - 170
And that is the answer.
Answer:
4 km/h
Step-by-step explanation:
We are told that Dina and Masha started out on a 10 km bike path at the same time.
Dina's biking speed is 5 km/h.
Let us find taken by Dina to cover 10 kn distance.




Therefore, Dina took 2 hours to complete 10 km.
Since both started at the same time, therefore, Masha also took 2 hours to complete 2 km less than Dina.
Let us find distance covered by Masha.

Now let us find Masha's biking speed.



Therefore, Masha's biking speed is 4 km per hour.
